每当我在Xamarin中运行iOS应用程序时,我似乎都会遇到此问题.

MonoTouch.Foundation.MonoTouchException has been thrown

Objective-C exception thrown. Name: NSInternalInconsistencyException Reason: Could not load NIB in bundle: ’NSBundle ... (loaded)' with name ‘RouteMeViewController'

我正在尝试使用我在其中开发的应用中的Objective C库和Binder用RouteMeViewController替换GoogleMapsViewController.我的AppDelegate看起来像这样：

namespace ExampleApp.iOS
{
[Register ("AppDelegate")]
public partial class AppDelegate : UIApplicationDelegate
{

    UIWindow window;
    RouteMeViewController viewController;

    public override bool FinishedLaunching (UIApplication app, NSDictionary options)
    {
        window = new UIWindow (UIScreen.MainScreen.Bounds);

        viewController = new RouteMeViewController ();
        window.RootViewController = viewController;
        window.MakeKeyAndVisible ();

        return true;
    }

}

RouteMeViewController

namespace ExampleApp.iOS
{
public partial class RouteMeViewController : UIViewController
{

    RMMapView MapView { get; set; }

    public RouteMeViewController () : base ("RouteMeViewController", null)
    {
    }

    public override void ViewDidLoad ()
    {
        base.ViewDidLoad ();

        MapView = new RMMapView(View.Frame, new RMOpenStreetMapSource().Handle);
        MapView.AutoresizingMask = UIViewAutoresizing.FlexibleDimensions;

        if (UIScreen.MainScreen.Scale > 1.0)
            MapView.AdjustTilesForRetinaDisplay = true;

        Add (MapView);
    }

}

}

非常感谢您的帮助或指导,谢谢！

解决方法:

似乎您的解决方案资源中缺少设计器文件.即使您以编程方式创建控件和视图,也需要一个需要在其中绘制设计器的文件,即使它只是一个空的设计器文件也是如此.对于IOS,您可以使用XCode.您可以创建带有.xib扩展名的文件.它们将在您的设备上编译,并且生成的文件扩展名为.nib.确保.xib文件的目标是项目的正确viewController,否则仍然会收到错误.

我希望这有帮助.祝好运！
